TMUX7219RQXR

Overview

The TMUX7219RQXR is a single-channel, 2:1 (SPDT) precision analog switch manufactured by Texas Instruments. It operates with a single supply voltage range of 4.5 V to 44 V or dual supplies from ±4.5 V to ±22 V. The device features latch-up immunity and supports bidirectional signal paths ranging from VSS to VDD. Key electrical characteristics include a typical on-resistance of 2.1 Ω, low charge injection of −10 pC, and high current support up to 440 mA in the WSON package. Logic inputs are compatible with 1.8 V signals, and the component functions within an operating temperature range of -40°C to +125°C.

Feature Summary

Latch-up immune design prevents high-current parasitic events caused by overvoltage conditions.
Fail-safe logic circuitry allows control pin voltages to be applied before power supply rails.
Break-before-make switching ensures signal path isolation during transitions.

Applications

Factory automation and industrial controls
Programmable logic controllers (PLC)
Analog input modules
Semiconductor test equipment
Ultrasound scanners

Procurement Notes

Verify the specific ordering suffix RQXR corresponds to the WSON-8 package configuration required for your PCB layout. Confirm that the logic level requirements align with your system's 1.8 V to VDD control interface specifications. Ensure thermal management strategies account for the junction-to-ambient resistance values provided in the datasheet for the selected package type.

Selection Notes

Select this component when high voltage tolerance up to 44 V is required alongside precision switching capabilities. The WSON package offers higher current handling compared to alternative packages. Verify that the break-before-make timing meets the system's signal integrity requirements during channel switching operations.

Part Context

This part belongs to the TMUX72xx family of CMOS switches designed for harsh environments. The RQXR suffix specifically denotes the WSON-8 package variant. This family emphasizes reliability through latch-up immunity and robust logic compatibility, making it suitable for demanding industrial and medical applications requiring precise signal routing.
